What striking tool is primarily used to drive bolts and chisels and to break rock?

The sledgehammer is specifically designed for heavy-duty striking tasks, making it the ideal tool for driving bolts, chisels, and breaking rock. Its large, heavy head allows for the application of significant force with each swing, which is particularly useful in tasks that require a powerful impact.

For driving bolts, especially those that are embedded in tough materials, the force delivered by a sledgehammer can ensure that the bolt is driven in effectively without needing excessive effort. When it comes to chiseling, a sledgehammer can provide the necessary impact to break through hard surfaces, facilitating the chiseling process.

In addition, when breaking rock or concrete, the sledgehammer is unmatched due to its weight and design, allowing the user to efficiently break apart stone or similar materials. Unlike lighter tools, such as a regular hammer or mallet, which might be more suited for delicate work, the sledgehammer is built for heavy-duty applications where substantial impact is needed.

This makes the sledgehammer the correct choice for the described functions, as it is specifically built for significant striking power, essential in, for example, construction and demolition work.
